FLUSHlNG-TANK FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 602,824, dated .April 26, 1898.

Application filed March 12, 1897. Serial No. 627,112. (No model.)

To all whom it may concern:

Be it known that we, CHARLES P. CARROL and JOHN I. GORMAN, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Flushing-Tanks for Water-Closets; and we do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to flushing-tanks for water-closets; and the invention consists of means whereby the tank is emptied and then automatically restored to its former conditions, substantially as described, and more particularly pointed out in the claims.

In the accompanying drawings, Figure l represents a cross-section of a flushing-tank with our improved mechanism therein and with the valve closed. Fig. 2 is a similar view, but showing the valve as just raised, with the parts remaining in this position until the float reaches the position shown in dotted lines, where the lever is then disengaged from the ratchet or gear wheel and the valve is allowed to close itself. Fig. 3 is a plan view of the tank and valves therein.

A represents a section of aiiushing-tank having the usual lioat B attached to and constructed to operate the water-supply valve B', Fig. 8. As is well known, the iloat after rising to a certain height shuts off the supply, and when the tank is emptying the float drops to a certain point, Where the water-supply is reopened and the outflow is stopped.

Our invention deals with the mechanism and valve which govern the outflow of the water from the tank. This valve A is constructed with a hollow stem 2, having a valveseat 3 at its lower end which seats itself on seat C and closes the outlet 4i of the tank. The construction of this valve-seat could be materially changed; but the present construction clearly shows the object of the invention. It is desirable to have the outlet as close to the bottom of the tank as possible, so as to utilize as much of the water in the tank as needed and at the same time have a construction and adjustment of parts which will overcome the gurglin g and other like noises which are such a detriment and serious objection to this style of iiushing-tank. We find that' by placing the outlet nearly flush with the bottom and so adjusting the valve as to close when the Water-level is still above the outletvalve an inch or two the sucking and gurgling noises are prevented, because the water remaining above the outlet is of such depth as to prevent the sucking in of air which causes such noises. When the water reaches the level shown in dotted lines, Fig. 2, the float has dropped to its lowest point, opening the water-supply valve and also closing the outlet-valve by the mechanism described, as follows:

The hollow stem 2 is held and is free to Work up and down in a casing or support 5, which carries a pinion or gear 6 and pawl or dog 7 on the extending arms S thereof. The stem 2 has arack 9 at its side, and gear 6 engages the teeth of this rack, and when it is desired to flush the closet and open the outlet of the tank the operator pulls the usual cord attached to one end of the pivoted arm 10 and which has its inner end linked to the top of stem 2, thus lifting the seat 3 and opening the outlet. To keep the outlet open until the requisite amount of water has been used, the gear 6 and pawl 7 are utilized as follows: The pawl 7 engages the teeth of gear 6 and has a counterweight l1 to keep the pawl locked at whatever point the operator may lift the rack and valve A. The lifting of valve and rack will rotate the pinion, and the pawl will automatically ride out of engagement, but be ready to engage by gravity the moment the lifting ceases, the pawl simply jumping the pinion-coge as this is done. This done, the valve is held up until the dog is disengaged by the descent of the float B, when it drops at once to its seat.

The arm 13 of pivoted pawl 7 must be actuated to lift projection l2 out of engagement with the teeth of gear 6, and this is done by the hook or projection 14, soldered on float B, which strikes the arm 13 when the water reaches a certain level, as shown in dotted lines of Fig. 2. This hook 14C can be soldered to any part or point of the iioat to get the desired adjustment and time for stopping the outliow of water. Instead of relying on gravv ity alone to close the outlet we could use a spring interposed between the casing and seat IOS 3 on stein 2 and so constructed as to close the outlet when gear 6 is released.

The valve-stem 2 is shown as being open throughout its entire length and as opening into the outlet. This provides a passage for an overliow in case the water-supply valve were to get out of order or if by chance the Water should rise abnormally in the tank. This makes it impossible for the water to overflow the edge of the tank, thereby avoiding much damage which Aotherwise might occur. The float B simply rises and falls Within the same vertical lines in the usual way, so that hook 14 will always engage with lever 7 when it descends and release when it rises.

What we claim as new, and desire to secure by Letters Patent, is-

l. A flushing-tank for Water-closets having an outlet and a valve to close the saine having a hollow stem, a rack on said stem and a gear engaging said rack, means to lift saidY valve and stem, a pawl to engage said gear and hold said valve in raised position, and a ioat having a projection constructed to release said pawl and allow said valve to drop to its seat, substantially as described.

2. A flushing-tank, and an outlet valve therefor, having a hollow stem with a rack thereon supported in a casing, a pinion supported in said casing and engaging said rack, a pawl pivoted on said casing and having a counterweighted end engaging said gear, and its other end construct-ed to be engaged by a projection on a float to release said gear, and a float having a hook to engage said pawl When the float descends, substantially as described.

3. The tank and the tubular outlet-valve stem having a rack rigidly connected therewith, and means connected directly to said stem to raise said stem and rack together, in combination with a pinion engaging said rack and a member to engage and lock said pinion when the valve is raised and thereby hold the valve in suspended position, and a free oat disconnected from said member and having a projection to engage and release said member when the float descends, substantially as described.

Witness our hands to the foregoing specification this 23d day of February, 1897.
